VICTOR BELANGER, OF SEAVIEIV, MASSACHUSETTS, ASSIGNOR TO ROTARY RING SPINNING COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORA- TION OF DELAWVARE.

SPINNING OR TWISTING MACHINE.

To (all 1071 0712, it may concern:

Be it known that I, VICTOR BI'ILANGER, of Seaview, in the town of Marshfield, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Spinning or Twisting Machines, of which the following is a specification.

This invention has relation to spinning or twisting machines of the class illustrated and described in my Patent No. 640,525, dated January 2, 1900; and it has for its object to provide certain improvements therein whereby the drag or traveler may be re volved at a greater rate of speed than was possible with my earlier construction. In my said patent is illustrated a spinning or twisting machine in which a rotatable ring on which the traveler revolves is mounted loosely, so as to yield under the unbalanced strains of the yarn, said ring being loosely confined within a casing mounted yieldingly upon the ring-rail.

I have found that apparently better re sults are achieved by the provision of a traveler which when the spindle is rotating at a relatively high speed will be caused by the tension of the yarn to frictionally engage or grip the ring, so as to insure that the ring will be rotated practically in unison therewith. At the same time it is requisite that the traveler should be so constructed as to revolve around the ring with a minimum amount of friction when the spindle is beginning to rotate or is rotating at a relatively low speed, for it is not until the traveler attains a certain rapidity of revolution that the inertia of the ring is overcome and the latter is caused to rotate with the traveler. I preserve the same bell shape of the ring that is illustrated and described in my previous patcut, but I increase the weight of the ring considerably, so that it requlres a relatively heavy strain on the yarn to draw it up from its seat upon the ring-rail, although it is free to move upward and also to move laterally when in rotation. So far as I have been able to ascertain a relatively heavy ring finds its center of rotation and maintains it more steadily than where a relatively light ring is employed. Again, in my earlier patent I have set forth a casing which is yieldingly mounted upon the ring-rail, as stated; but I find I can attain still better results by placing inside of the said casing a pacln'ng or Specification of Letters Patent.

cushion of suitable material in the nature of a fabric-such as canvas. By the employment of this packing or cushion the ring seems to run more steadily than heretofore and may be rotated at higher speeds than seems to have been possible with the earlier construction. I preferably construct the casing of tin or suitable metal or composition, since it may be stamped or died into shape, said casing being provided with apertured cars, which are socketed to receive cushioning material, through which a screw is passed into the ring-rail and which holds the casing yieldingly in position on the rail.

Reference is to be had to accompanying drawings, which illustrate one embodiment of my invention.

Figure 1 represents in front elevation a bobbin and spindle and portions of the ringrail having my invention thereon,-a threadeye or pigtail, and a portion of the top drawing-rolls. Fig. 2 illustrates in enlarged plan view a portion of the ring-rail with the improved traveler-ring and ringcasing thereon. Fig. 3 represents a section through the same on the line 3 3 of Fig. 2. Fig. 4 illustrates the position the traveler assumes when the ring is at rest or when a spindle is rotating slowly. Figs. 5 and 6 represent perspective views of the ring-casing. Fig. 7 represents a perspective view of one form of traveler. Fig. 8 represents a perspective view of still another form of traveler. Fig. 9 represents the position assumed by the traveler shown in Fig. 8 when the ring is rotating at a high rate of speed.

The same reference characters indicate similar parts or features, as the case may be, wherever they occur.

Before I proceed to describe the invention in detail it will be understood that it may be employed in connection with a spinning or twisting machine of any pattern or type and may be used as well for twisting cord or rope as for the spinning of fine hosiery-yarns. I have shown, however, in Fig. 1 a portion of a spinning-machine in which 10 10 represent the drawing-rolls, 11 represents the yarn guide or pig-tail, so called, 12 represents the ring-rail, 13 indicates the spindle-rail, 14 indicates the spindle, and 15 indicates the bobbin on the spindle. The yarn is indicated at 16 and passes from the delivery or drawing rolls through the pig-tail 11 and through the traveler on the ring to the bobbin. The bobbin maybe driven by any suit able power-transmitting devices, such as bands, tapes, cords, or belts, (indicated. at 17.) The ring-rail 12 is apertured in the usual manner, as shown in Fig. 3, and upon it is loosely secured a casing, (indicated as a whole at 18.) This casing is preferably formed in two sections, of which one is stam ed or died out of tin or other suitable meta and the other is preferably made of wood-pulp, fiber, or any suitable composition. The upper section of the casing has a circumferential wall 19, with the beveled top flange 20, the wall 19 and flange 20 constituting, in effect, a concave surface to inclose the ring. Extending laterally from the ring are two diametrically opposite ears or lugs 21, which are provided with enlarged apertures 22. Each ear or lug has a circumferential upwardly-projecting wall 23 to form a socket for the reception of a plurality of disks 24, of wool, felt, rubber, or other suitable cushioning material. Large-headed screws 25 are passed through the disks of cushioning material and through the apertures in the lugs 21, so that while the casing is held upon the rail a ainst displacement it is free to yield latera ly (or in a plane parallel to the plane of the ring-rail) or else vertically, (or in a direction perpendicular to the ring and said rail.)

The lower section of the casing is indicated at 26, being flat and in the shape of a ring,'

its internal diameter being less than that of the top section, so that there is provided an annular chamber with a flat bottom wall and an inwardly-inclined side wall, in which the ring may be confined. The lower section of the casing is provided with ears or lugs 27, through which the screws 25 pass, and which is held against movement by shoulders 28 on said screws.

Within the upper section of the ring-casing is placed a suitable packing 29 of suitable material, such as canvas, which covers the entire surface of the wall 19 and flange 20, as shown in Fig. 3. This is secured in place by any suitable means, such as cement or glue, and it is generally covered with a coating of shellac or varnish.

Within the chamber formed by the casing is placed a bellshaped ring, (indicated as a whole at 30.) It is provided with an upwardly-projecting flange 31 and a similar downwardly-projecting flange 32, which are exteriorly beveled from the edge toward the middle portion for a purpose to be described. The bell-shaped portion 33 of the ring is substantially in the shape of a truncated cone, and it fits loosely within the casing, having a flat base which rests upon the lower section of the said ring-casing. The ring is preferably formed of steel and is relatively heavy, as shown, being, however, light enough to prevent its moving with any considerable friction against the lower section of the casi11 The traveler may be constructed in a variety of ways to rotate about the ring, but I prefer to so construct it that when the bobbin is initially rotated it will be revolved about the ring with a minimum. amount of friction, which friction, however, will increase as the strain of the yarn increases, so as to assist the traveler in. overcoming the inertia of the ring and causing it to rotate practically in unison therewith. To this end the traveler, which is indicated as a wholi': at 34, is provided with a lower bent end 35, which takes under the wedge-shaped flange 32, with a relatively straight portion 36, which projects upward through the ring and is adapted to bear against the inner surface thereof, and with a top bent portion 37 which forms the thread-eye and which projects over the upper wedge-shaped flange 31 of the ring.

The extremity of the upper end of the traveler is adapted to bear against the top of the ring near the base of the flange 31 and in Fig. 7 is shown as having an upturned portion 38 to assist in threading the yarn through the eye.

The traveler is preferably formed of a flat strip of steel; but it may be formed of round or cylindrical wire, if desired, although so far as I am able to ascertain I secure better results with the construction shown.

When the ring and the bobbin are quiescent, the traveler hangs loosely, as shown in Fig. 4, with its upper end resting upon the flat middle portion 39 of the ring, and when the bobbin is initially rotated the traveler revolves around the ring with an apparently light friction, since the tension upon the yarn is not very great; but as the speed of the bobbin increases and the yarn is caused to balloon more and more the tension on the traveler increases proportionately, and the latter is drawn into the position shown in Fig. 3, where it is wedged tightly against the lower flange and the inner surface of the ring, and the ring is therefore caused to move sub stantially in unison therewith.

The beveling of the lower flange of the ring causes the wedging action just described, while the beveling of the upper flange presents a surface upon which the upper end of the traveler may rest when the ring and bobbin are quiescent, as in Fig. 4:, said upper end of the traveler leaving said surface almost at once when the bobbin is initially rotated. In other words, the beveled surface of the upper flange of the ring holds the traveler quiescent in such position that it will have to swing outward but slightly after rotation commences before the wed in action begins,

due to the beveling of the low er flange. By

thus increasing the friction of the traveler upon the ring to cause them to move in unison there is in the end less rubbing of one of the parts against the other to cause the wearing away of the traveler than there would be if the ordinary traveler were employed, and consequently a single traveler may be used for a much greater period of time than heretofore, since it has always up to the present time had to endure a certain amount of constant friction during the operation of the spinning-machine.

The strain of the yarn is practically mainly upward, though to some extent outward, and consequently the traveler is wedged more or less tightly against the ring, and as it is relatively flat the yarn tends to slightly twist it to hold it still more tightly in place.

It is evident that the traveler may be constructed in a variety of ways, as previously stated, and in Fig. 8 I have shown another form which I sometimes employ with excel lent results. Practically the only difference between the two constructions is that the one shown in Fig. 8 is provided with an in wardly-projecting end 40 instead of the out wardly-curved end 38; but so far as I have been able to ascertain the two operate in substantially the same way, both being formed of flat metal and having the lower bent end and the upper bent portion to form the thread-eye and to take over the ring.

hen the bobbin is rotating at a relatively high rate of speed-say sixteen thousand to eighteen thousand turns per minute-the ring moves with such steadiness that it is diflicult to tell whether or not it is rotating, and this appears to be due to the fact that the movable ring-casing is provided with a cushioning-packing, as well as due to the fact that the ring is relatively heavy and requires con siderable strain to move it bodily from its axis of rotation.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without having attempted to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1. The combination of a rotatable ring capable of radial movement relatively to the spindle under stress of the yarn, a casing for limiting the movement of the ring, and a packing between the ring and the casing.

2. The combination of a rotatable ring capable of lateral movement, and a casing for limiting the movement of said ring, said casing having a lining or packing on its inner surface.

3. The combination of a rotatable ring capable of lateral movement, and a casing for limiting the movement of said ring, said oasing having cushioning material on its inner surface.

4. The combination of a rotatable ring capable of lateral movement, and a casing for limiting the movement of said ring, said casing being lined with fabric.

5. The combination of a rotatable ring capable of lateral movement, and a casing for limiting the movement of said ring, said casing being formed of metal and having an internal lining of relatively softer material.

6. The combination of a rotatable ring capable of lateral movement, and a casing for limiting the movement of said ring, said cas ing being formed of metal and having a lining of canvas or equivalent material.

7. The combination with a rotatable ring freely yielding under unbalanced strains of the yarn, of a casing died out of sheet metal and having an internal lining or packing.

8. The combination of a rotatable ring, and a traveler adapted to revolve about said ring, said ring and traveler having provisions whereby they are wedged together as the tension on the traveler is increased.

9. The combination of a rotatable ring, and a traveler adapted to revolve about said ring, said ring and traveler having provisions for increasing their frictional engagement.

In testimony whereof I have affixed my signature in presence of two witnesses.
